FIRE-EXTINGUISHER.

EBCIFICATEON forming part of Letters Patent No. 373,563, dated November 22, 1887.

Application filed March 28, 1887. Y Serial No. 232.651. (No model.)

To all whom may concern:

Be it known that I, LEROY S. LEWIS, of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Fire-Extinguishers,of which the following is a full, clear, and exact description,whereby any one skilled in the art can make and use the same.

My improvement relates more particularly :o to the class of portable chemical fire-extinguishers, and its object is to provide an improved looking device to regulate the turning of the rotary Crusher-spindle of the kind shown and described in myUnited States patent granted July 20, 1886, and numbered My improvement consistsin the combination, in a fire-extinguisher, of the rotary Crusherspindlc with the projectingr arm, the outletzo tube of the nozzle having a cock or valve, the

handle of which bears a device adapted to engage the arm ot' the spindle, whereby the latter is locked against rotation; and it further consists in the spindle-locking device in combination with a stop that limits. its outward movement; and it still further consists in details of the several devices and their combination, as more particularly hereinafter described, and pointed out in the claims.

Referring to the drawings, Figurel is atop View of an extinguisher embodying my improvements. Fig. 2 is a side view of thesame in elevation, with parts broken away to show construction. Fig. 3 is a detail View in section through the outletyalve and its handle,

on plane denoted by line x of Fig. 2.

In the accompanying drawings, the letter a denotes the vessel that holds the iireextinguishing iiuid; b, the cover ofthe Vessel; @,the

4o outlet-tube, and d the Crusher-spindle, having on its upper end the projecting arm d, located at a suitable distance above the cover, and by means of which the spindle may be'rotated. These several parts oi' the device and the construction of the inside of the vessel and of the crushing device are clearly shown and described in my prior patent above referred to, and are not material to my within-described improvement, that may, however, be applied as well to other extinguishers having the outlet and Crusher-spindle.

Near the nozzle of the outlet-tube is arranged a valve 0r cock. c, with the valvcplug c arranged across the pipe in a plane at right angles to the axis of the Vessel, so that in the opening and closing movement of this rotary plug its handlef will swing from and toward the crusher-spindle. This valve-handle is (in the form shown in the drawings) forked, so as to be attached to the valve-plug on opposite sides of the valve-body that forms a part of the outlet-tube. Each of these arms is in turn forked, so as to fit upon the squared portion of the plug, and each is provided on the side toward the plug with a projection or lug, f', that is adapted to fit into the socket]2 in the side of the plug. The object of this interlocking device isto enable the handle to be fitted upon the plug and held there by the lug f', being held in the socket by the nuts g, that are screwed upon the threaded outer ends of the valve-plug.

I do not limit myself to this specific construction of' the handle of the plug, nor its method of attachment, as the handle may be attached to one or both ends of the plug by any means without departing from my improvement. The outer end of this valve-han dlef has asocketon the side toward the valvespindle, and the projecting arm of the latter enters the socket when the handle is thrown over against it. In the position of the parts that is shown in full lines in Figs. 1 and 2 the crusherspindle is securely held against rotation until it is released from the hold of the locking device h, from thehold ofwhich, however, it may be released by pushing outward upon the thumb-piecef3, formed on the outer end of the valve-handle. The outward play of this valve-handle may be limited by its striking against the brace z', that serves the purpose oia stop for the handle, and also to more securely fasten the outer end of the out- 'let-pipe to the side of the vessel.

The opening through the valve-plug is so 9 formed that the valve is opened to its full extent when the valve-handle is at the outward limit of its play, and is completely closed when the valve-handle is used in its function as a look for the Crusher-spindle and is at the inner limit of its play.

The operation of my improvementis so obvious as not to need extended description.

I claim as inyinventionl. In a fire extinguisher, in combination with the rotary'bottle-crusher spindle,the outlet-tube having a valve or cock located outside of the vessel, the handle of which is provided with means, substantially as described, for engaging the Crusher-spindle, and whereby the latter is held against rotation when engaged with the handle of the outlet-valve, all substantiall y as described.

2. VIn combination,in a fireextinguisher,the crusherspindle d, having the arm d on the end outside of the vessel, andthe outlettnbe @,With the valve e,having arotary plug, e', with its handle f, the latter having the socket adapted to engage the end of the arm of the Crusher-spindle, all substantially as described.

3. In combination, in a reextinguisher, the Crusher-spindle d and the outlet-tube c, having a valve, e, With the handle fast to the plug of the valve, and having asocket adapted to engage the spindle7 and when in engagement with it to prevent the rotation of the 3o spindle d, all substantially as described.

4. In combination with the portable vessel a, the Crusher-spindle d, with handle d', the outlet-tube o, the cock or valve e in the outlet-tube, and having a rotary plug, fast to 3 5 which is the forked handlef, and the handle with the lugsf, fitting the socketsf2 in the body of the plug, and having also the socket adapted to receive and hold the arm of the rotary Crusher-spindle, all substantially as de- 4o scribed. 4

5. In combination with the outlet-tube of ahw-extinguisher, a valve having a handle fast to the plug of the Valve', the stop that limits the swinging play of the handle When the 45 Valve is open, and the arm ofthe crusherspindle engaged by the handle when the valve is closed, and the Crusher-spindle, all substantially as described.
